ELECTRICAL CONNECTER'.

Application led November 10, 1921. Serial No.4514,231.

To aZZ whomz't may concern.' y

Be it known that I, ALFRED E. LATHAM, acitizen of the United States, anda resident of the city of New York, boroughof Brooklyn, in the county ofKings and State of New York, have invented a new and Improved ElectricalConnecter, of which the following is' a full, clear, and exactdescription.

This invention relates to an electrical connecter, and has for an objectthe provision of means whereby a circuit wire may vbe simply but verysecurely fastened within the connecter so that it will stand greaterstrains and will make a much more eilicient elec trical Contact.

Another object resides in th particular construction and arrangement ofparts which are hereinafter described and claimed and* shown in theaccompanying drawings.

The invention 'is illustrated in the drawings, of which- Figure 1 is alongitudinal section taken Fig. 2 is a side elevation showingthe twoparts of the connecter spaced apart.

Fig. 8 is an end view of the plug portion of the connecter. u

The drawings illustrate a preferred form. of my invention but it isunderstood that modifications in the arrangement 'andfconstruction ofthe parts may be adopted without departing from the general spirit ofthe y inventiony as set forth hereinafter.

This invention as shown in the drawings comprises a socket portion A anda plug portion B. The socket portion comprises a shell 1 of any suitableinsulating material, v such as ebonite, having disposed in a suitableportion therewithin a metallic socket body portion 2. This socket isprovided with a bore 3 threaded as at 4: along its outer edges andprovided with a curved shoulder 5 at an intermediate portion. This boreis reduced toward the inner end, as at 6, and is provided with ashoulder l7, Aand beyond this is still further reduced as a 'small bore8. Midway of the body portion of the socket 2 are bayonet pins 9 and 10which extend in opposite directions therefrom through the ebonite shell1 to forni'means for fastening the connecter to any suitableco-operating member. .A contact pin l11 extends through the aperture orbore 8 and has a ange 12 thereon engaging the shoulder 7. This flange isbacked by a spring 13, the

tion of said head to engage with the threads other end of which bearsagainst wires 14. These wires passthrough a bore 15 in a metal plugportion andare bent around over the end thereofv to be gripped betweenthe projecting portion 17 of the plug and the walls of the socket andtobear against the curved shoulder 5 previously mentioned. The projectingplug portion 17 is provided with threads to engage in the threaded bore4.

rI he plug meinberis provided, likewise, with an insulating body portion18 provided with a knurled ring flange 19 and at its front end with adepressed recess 20 into which the end of the shell 1 extends as theplug portion 16 is screwed into the socket portion 2. The plug portion16 and the insulating body portion 18 are provided with aligningapertures forming the bore 21 through which the conductor 22 extends.conductor is stripped so that the wires maypass through the bore 15 withtheir ends bent .over and contacting alongthe outer surface of theprojectmg portion 17.

cess 20 embraces the end ofthe shell 1, the

joint between the body portion 18 and the socket 2 is very perfectlyinsulated by the engagement` of the insulating shell. y

In this manner I have provided. a simple, eliicient connecter devicethatcan Vbe readily y disassembled, and when assembledl forms a compactstructure in which the wires are` very firmly and strongly gripped.

What I claim is:

1. An electrical connecter which comprises a conducting socket portion,a sleeve of insulating material surrounding the same, said l The end ofthe Vsocket portion having 'an interior bore threaded at one end, a plugportion of conductin material,- a sleeve of insulating material terearound, said lastmentioned sleeve on the face adjacent the socketportion havl ing a recess into which the end of the iirstmentionedsleeve extends,`said plug having a projecting head to extend into thebore of the socket portionand threaded along a por- 1 inthe bore of thesocket whereby the socket member and the plug member are tightlyengaged.

2. An electrical connecter'whieh comprises a conducting socket portion,a sleeve of insulating material surrounding the same, said socketportion having an interior bore threaded at one end, a plug portionofconducting material, 'a sleeve of insulating material therearound, saidlast mentioned sleeve on the face adjacent the socket portion having arecessinto which the end of the firstmentioned sleeve extends, said plughaving a projecting head to extend into the bore of the socket portionand threaded along a portion of said head to engage with the threads intheb'ore of the socket whereby the socket member and the plug member aretightly engaged, said extending head portion having a bore therethrough,and conducting wires eX- tending through said bore and beyond the end ofthe head, said Wires being bent backwards along the outside surface ofthe head to b-e gripped between the Walls of the socket and the head. n
